Title: Boiling water reactor
Inventor: ORII AKIHITO
IPC: G21C5/00
Filed: 1994-07-19
Abstract: PURPOSE:To obtain a reactor in which the reactor core can be controlled by means of a control rod without shortening the effective heating length thereof while lowering the height of pressure vessel. CONSTITUTION:The position of a fuel pellet 32 is shifted upward and a gas plenum 33 is provided at the lower end of a control rod. The full draw-out position of a control rod 13 is set such that the upper end of the neutron absorber 13a thereof is located below the fuel pellet 32. The full insertion position is set such that the upper end of the neutron absorber 13a is located above the fuel pellet thus preventing interference of the control rod with a fuel supporting metal 12 and a channel fastener 21 during the stroke preceding the full insertion. Since the height of pressure vessel can be reduced by shifting the position of control rod upward and shortening the control rod guide pipe, the reactor building can be made compact resulting in the enhancement of the utilization efficiency of site and the economy.

Moreover, a thermoplastic resin sheet is laid on the surface on the side, where the bonding agent 3 is not held, of the substrate 2 and is heated and pressed, whereby a multilayer printed board is formed. In this process, the thermoplastic resin sheet begins to soften and is filled in the hole part 2b in the board 2. Then, the bonding agent 3 is molten, but as the thermoplastic resin sheet is filled in the hole part, the bonding agent 3 does never squeeze-out in the hole part.
